Abstract

Sphygmomanomètre automatique permettant de mesurer la tension arterielle d'un sujet à partir des bruits de Korotkoff et de déterminer les valeurs supérieure et inférieure maximales possibles de la tension artérielle par l'analyse des variations d'amplitude des signaux des pulsations du signal détecté au niveau du brassard et de vérifier si les tensions déterminés par l'application et la despiration des bruits de Korotkoff sont comprises entre les limites susmentionnés. Ce sphygmomanomètre est pourvu de préférence de deux systèmes de circuits amplificateurs-filtres correspondant aux caractéristiques de fréquences des signaux de bruit de Korotkoff proches de la plus haute tension et de la plus basse tension et d'un circuit discriminateur fondé sur une valeur de seuil, de manière à rendre plus précise l'application de chacune de tensions haute et basse. De préférence, ces deux systèmes et ces signaux de seuil sont rendus accessibles et contrôlables de l'extérieur pour permettre le calibrage d'un sphygmomanomètre électronique par l'utilisation simultanée d'un stéthoscope.
